I don't know this lens, but if it carries the Carl Zeiss name, it's surely not going to disappoint you.

The Flek 2.4/35 is a good lens, but given the prices it is sold currently for, with the same money you can buy a Zeiss Distagon 2.8/35 which is a better lens, up there with the best 35mm, and the best of all when distortion (or better said lack thereof) is concerned._________________Orio, AdministratorT*NE CEDE MALIS AUDENTIOR ITO
